The New Arms Race: DDR3-1800 RAM

Processor: Intel Core 2 Duo E6750

Our Core 2 Duo E6750 was capable of running at up to 530 MHz FSB speed (FSB2120) and beyond 3.3 GHz core clock speed. We reduced the x8 multiplier to x6 for our testing to avoid the CPU core becoming a bottleneck.

For Comparison: DDR3-1333 At JEDEC Standards

To have a performance comparison between the two DDR3-1800 DIMMs and conventional DDR3 memory at the same FSB and core clock speed, we used the OCZ memory and reduced the clock speed to DDR3-1350 (this was as close to 1333 as we could get) at CL9-9-9-26 timings. This resembles the JEDEC requirements for DDR3 memory at 1333 speed. Most retail PCs that weren't designed for enthusiasts are typically equipped with this sort of standard memory.
